A research was conducted to clarify the bioavailability and uptake of chromium in earthworms, carabid beetles and shrews in the surroundings of stainless steel works located in the Northern Finland. Within the study area chromium and other metal contaminants have accumulated into the soil system due to four decades of aerial depositions from the industrial activities. The effects of multiple metal exposure were also studied in shrews, and some population parameters were measured to receive a more holistic understanding of the wellbeing of the animals in the metal contaminated area. Based on the results it is concluded that part of the chromium loading in the soil humus layer, although a relatively small fraction compared to total concentration, is available for uptake by the study organisms. In general, earthworms were found to be most affected by the elevated metal concentrations, in particular within one km distance from the works. There was also some indication of adverse effects in carabid beetles. However, relatively limited responses were observed in shrews.
